Oracle and SUN Engadget got the chance to sit down with Jonathan Schwartz, the pony-tailed CEO of Sun Microsystems. Being the gadget blog that they are, Engadget asked Schwartz about the long-missing JavaFX Mobile platform Sun has promised, Java on the iPhone, and competing with Microsoft as an open source vendor.

RE[6]: Shame ...

Member since:

I really hope all Sun customers have your kind of faith. Really. I do.

Stick to the point.

Repeating and regurgitating Sun's own benchmarks, verbatim, counts for very little.

Are you just daft? HP and Sun both submitted their respective results to Spec. It doesn't get any more objective than that.

On raw performance? Four Xeons versus one SPARC, all at twice the clock speed (not that that counts for much as a comparison)? Errr, no.

Your ignorance is even more telling. Cpus consume more energy at higher clock rates and dissipate more heat.

But you keep telling yourself that. One SPARC would never keep up with one Xeon in a month of Sundays, and the sorts of target workloads that Sun seems to be using would have to be so parallel and so concurrent as to be totally unrealistic. Not everything is or can be, and even in the article I linked to the UltraSPARC couldn't even outperform the Opteron on that.

Your article was ridiculously out dated. SpecWeb is an industry standard benchmark. Prove your point with some real data not FUD.

I'm sure Sun can find lots of other completely arbitrary, moving target units of measure such as 'performance per watt' to make SPARC look better. Whether that is really enough, we'll have to see. Something tells me that Sun hasn't learnt from what happened after the dot com boom.

Again, specweb is a real benchmark for web services ( the target market for the Sun box) and and single Sun chip out classes 4 of the latest Xeons.

Right on cue. Speaking of arbitrary units of measure...... You can't just tot things up on Sun's power calculator on their web site and expect that to answer a real world question.

More vile ignorance. Real world datacenters are constantly looking for ways to reduce their cooling and electricity bills. Gee I wonder why virtualization and server consolidation is big in the REAL WORLD.

I forgot that you don't live in the real world.

It doesn't. It would help if you actually looked at what the results tell you, and it would also help if you actually knew what the power consumption cost of a Xeon was. You balance that versus the raw performance, and you could halve the CPUs to two and halve the performance of a Xeon to cut power right back (a more realistic test) and its raw performance would still be better.

It doesn't? Say what? that doesn't make any sense.

The Xeons X7350 are 130W parts. HP's and Intel's websites say so. Can't you read and comprehend?

Even if you reduce the cpus to 2 you get 260Ws for the cpus alone vs 95 watts or at max 123Watts for the SPARC cpu box. The SPARC box is still lower power but can now deliver twice the performance of the HP Xeon Box.

What people are looking at is whether it is worth spending the money to get any future power savings, versus having the raw performance per cycle. Nobody cares about Sun's theoretical performance per watt. Fact is, compared to an Opteron box, the guy worked out that his UltraSPARC would have to be at least twice as power efficient to feel the effect of cost savings over a period of several years for Coolthreads to be worth it. Sorry, but that scenario doesn't add up.

Eh? The Sun box and the HP box cost almost the same and the Sun box uses significantly less power.

Oh you are still stuck like a broken record on that article you posted.

I think HP and its engineers tuning the hell out of their setup and submitting a result that show cases the best performance number on SpecWeb2005 and Sun doing the same counts for a lot more than a blog post from 2 years ago.

HP and Sun have the only two results in the 40K range on SPecWeb2005. So we are comparing the very best submissions from the respective companies.

You can't possibly be implying that HP doesn't know how to tune and get the best performance out of their systems, could you? Especially when they are trying to post the highest number, or so they thought, for their own customers to see and the sales staff to use as material sell those systems.

You certainly can't be that daft , can you?

Hate to break it to you, but the raw performance of SPARC has lagged behind x86 for a very, very long time.

Got proof? The cool threads server's perfomance throws a wrench soundly in that statement.

I'd laugh if that wasn't so sad. Why do you think they left in the first place? I'm sure Sun gave them a nice deal and some new toys to play with ;-).

Please don't show your stupidity any more than you have to.

The issue here is how much of each thread can be completed per second (is it better to get more threads and work through each second, or is it better to have more of them?) versus the initial cost of the machine versus the time it takes for the power cost savings to outweigh the initial cost. That's what matters.

More nonsensical gibberish. Read and comprehend first. Then do some research and come up with some real data to the topic at hand. Some up to date data would be very useful.

Coolthreads (and multiple cores in general) is simply a tough sell for people wanting to complete more of the same tasks in less time following Moore's Law, and that accounts for the majority.

I wonder why the coolthreads systems are doubling in revenue YoY.
